4. The Invasion of Russia
The 1812 invasion of Russia stands as one of history’s most catastrophic military blunders. Napoleon’s Grand Army, initially numbering over 600,000, was devastated by brutal winter, starvation, and the Russians’ scorched earth tactics.
This campaign echoes other infamous disasters, such as the defeat of the Spanish Armada or Charles XII’s failed assault on Russia. According to Smithsonian Magazine, fewer than 100,000 men returned, shattering the myth of Napoleonic invincibility.
